Engineering Selection Recommendations

All listed substitute parts maintain mechanical and electrical compatibility with the 55510-312 across the core substitution parameters: 12-position receptacle configuration, 0.079" (2.00mm) pitch, surface mount solder termination, and push-pull fastening.

Hirose A3 series (A3-12DA-2SV(71) and A3A-12DA-2SV(71)) are active products with ROHS3 compliance. These parts operate at -55°C to 85°C, which is narrower than the original 125°C upper limit. The A3A variant includes board guide features. Current rating is 1A per contact, lower than the original 2A specification.

Samtec MMS-106-02-S-DV-P-TR provides the highest current capacity at 3.9A per contact and maintains the full -55°C to 125°C operating range. This part includes pick-and-place features and uses Liquid Crystal Polymer insulation.

Samtec TLE series (TLE-106-01-G-DV-A-P-TR, TLE-106-01-G-DV-A-TR, TLE-106-01-G-DV-K-TR) are pass-through receptacles with 3.2A per contact current rating and full -55°C to 125°C temperature range. All three variants are ROHS3 compliant and active products. TLE-106-01-G-DV-A-P-TR and TLE-106-01-G-DV-K-TR include pick-and-place features; TLE-106-01-G-DV-A-TR includes board guide features.

Frequently Asked Questions (FAQ)

Q: Can the Hirose A3 series parts directly replace the 55510-312 in all applications?

A: Hirose A3 series parts are mechanically and electrically compatible for the core connector function. However, the operating temperature range is limited to -55°C to 85°C versus the original -55°C to 125°C. Applications requiring operation above 85°C require Samtec alternatives. Current rating is 1A per contact versus 2A on the original part.

Q: What is the difference between standard receptacle and pass-through receptacle designs in the Samtec TLE series?

A: Pass-through receptacles allow signal routing through the connector body, enabling daisy-chain or multi-level stacking configurations. Standard receptacles terminate signals at the connector interface. Both designs maintain identical pitch, position count, and mating interface dimensions.

Q: Are all substitute parts available in the same packaging as the original 55510-312?

A: The original 55510-312 packaging is not specified in the provided data. Hirose A3 series parts are supplied in tube packaging. Samtec MMS and TLE series parts are supplied in tape and reel (TR) format, suitable for automated pick-and-place assembly.

Q: Which substitute part offers the best current-carrying capacity?

A: The Samtec MMS-106-02-S-DV-P-TR provides the highest current rating at 3.9A per contact. Samtec TLE series parts provide 3.2A per contact. Both exceed the original 2A specification and support higher-power applications.

Q: Do all substitute parts meet RoHS compliance requirements?

A: Hirose A3 series and Samtec TLE series parts are ROHS3 compliant. The Samtec MMS-106-02-S-DV-P-TR RoHS status is not specified in the provided data. The original 55510-312 is RoHS non-compliant.
